The report, from the National Center for Health Statistics branch of the U.S. Centers for Disease Control and Prevention, documented declines in the three areas: The teen birth rate fell to 31.3 births per 1,000 women aged 15 to 19 in 2011. Twenty years ago, that rate was 61.8 per 1,000 teenage girls. And, for the fifth straight year, the preterm birth rate dropped, to 11.7 percent in 2011 from 12.8 percent in 2006. The rate for low-birth-weight babies also declined, from 8.15 percent in 2010 to 8.1 percent in 2011.
The report was published online Feb. 11 and will appear in the March print issue of the journal Pediatrics.
